K-nuts are typically used to secure:

Brake parts: brake caliper to the caliper mount, rotor to the rotor hat, master cylinders to the pedalbox...

Other applications: turbo manifold to cylinderhead, areas with limited space, high heat areas...

#1 motorsport nuts

The K-nuts are used across the motorsport disciplines.
We mostly sell them for rally cars (WRC, S2000, R3...) and circuit racing cars (touring cars, GT cars...), but they are also used in formula cars (F1, F3...), karts and racing motorcycles.

metric and UNF K-nuts

We cover a complete range of metric K-nuts with coarse pitch thread as well as fine pitch thread. The most common metric sizes for K-nuts are M5, M6, M8, M10 and M12. However we also consider the sizes M3, M4, M7 and M14 as standard. 1/4"-28 UNF, 5/16"-24 UNF and 3/8"-24 UNF are the common sizes of the UNF threaded K-nuts.
